Just wondering who has a good stroker crank out there right now.  I think you can go with a +8 before trenching the cases correct? 

Wondering about stroker vs long rods.  I would prefer a long rod.  And how much?

Then...who wants to install it  :rofl: :clap:

Jason had told me you can go +11 without any trenching worries..... and for the +15 it only took about .040 thou off the crank.... which they can also do inhouse for a small fee

I have a +12 Barker Billet. Rocket Factory put the whole thing together. Its a long Rod so it also requires a 1/2" spacer. I also had them do the install and the whole build went flawlessly. I would definitely recommend you go with the Long Rod Crank as well as the Rocket Factory.

They add a spacer to the bottom of the Jug. This allows you to run a longer rod witch inturn lessens the rod angle. On my build now my rod angle is less then stock. It russ smooth with less vibration then when it was brand new but a ton of TQ. I think it did 72fp on Jasons Dyno.

So would that be 32 on every other dyno.   :rofl: 

Just kidding bro.   :lol:

I'm real curious to see the TQ it's makes on Rooster Builts dyno......I love stump pulling torquey builds.......this will give me a great comparison to my 60+ ft lbs of TQ I made on the same dyno with my 780 and help me determine a future upgrade path  :thumbs:

I'm very interested in these long rod builds.  I wonder if they are more reliable then the common builds.

If you have to add a 1/2" spacer to the cylinder then how does the motor still fit in the frame. Do you have to mod the top motor mounts or what?

I have no clue.  I'm still learning about these builds.
